Answer 1

Tables must be in InnoDb format. MyISAM format of tables doesn't support transactions.

No need to insert additional code into model.

ProductController:

$datasource = $this->Product->getDataSource();
try {
    $datasource->begin();
    if(!$this->Product->save($data)
        throw new Exception();

    if(!$this->Price->save($data_one)
        throw new Exception();

    if(!$this->Property->save($my_data)
        throw new Exception();

    $datasource->commit();
} catch(Exception $e) {
    $datasource->rollback();
}
